The bulb
that cost a house
On 3 February 1637, in Haarlem, an auctioneer could not find a single buyer for his tulip bulbs, however far he lowered his price. Two days later, an orphanage in Alkmaar sold a lot of tulips for ninety thousand guilders, the largest sum the market had ever recorded: the record and the collapse played out forty-eight hours apart.
The price of a bulb, the price of a house
From the early 1630s the Dutch Republic grew infatuated with rare tulips streaked red and white by a virus nobody could yet identify. The most sought variety, Semper Augustus, rose from 1,000 guilders in 1624 to 5,000 in 1633, then to 10,000 at the January 1637 peak: enough to buy the finest house on an Amsterdam canal, or ten times a skilled artisan's yearly income.
Speculation soon spread beyond the growers themselves. Wealthy merchants and craftsmen traded, in tavern back rooms organised into "colleges," promissory notes on bulbs still in the ground: windhandel, "wind trade." On 3 February, in Haarlem, a lot found no buyer at any price. On the 5th, the Alkmaar orphanage pocketed its record sum, unaware the market had already gone silent elsewhere. Within days prices fell to 5%, sometimes 1%, of their January value; by the 7th, growers in Utrecht were already organising to try to contain the panic.
No one posted a deposit or a margin call: every contract bound two individuals, not an exchange. Only a fixed 2.5% fee, the "wine money," went to the tavern keeper, whatever became of the trade.
The story outlived the losses
Since Charles Mackay's scathing 1841 account, tulip mania has served as the fable for every speculative bubble: a whole nation ruined by flowers. The notarial archives say something else. Historian Anne Goldgar found only a handful of traders in real financial trouble after 1637, and it isn't even clear tulips were to blame. Because most windhandel contracts were never honoured, neither bulb nor guilder had, in many cases, actually changed hands: the wealth "lost" had, for the most part, never existed anywhere but on paper.
What the crash truly cost was a narrow circle of prosperous merchants and craftsmen, not the Dutch economy as a whole, then near its peak. The legend of a national catastrophe outlasted the ledgers themselves: a moral story, once fixed, is harder to correct than a price.
A bubble always leaves two traces: accounts that never quite balance, and a story no one has any interest in correcting.
